I received my 52cc strimmer today, on the day sgs said it would be delivered. It took me 20mins to assemble it, which was extremely straightforward and relatively easy. Added 40:1 mixture, pressed the feed bubble until no air in fuel pipe, full choke, pulled, it coughed, moved choke to half way, pulled again and it started, moved choke to normal running position and commenced strimming for a good hour without the slightest hiccup. I read lots of reviews on Amazon stating it wouldn't start or very difficult to start, not worth the money, rubbish, this is and outstanding workhorse and if you follow the process I did above, it will start every time without a problem.
